The Flex Lens Shade is a flexible lens shade that can be easily attached to any lens to block unwanted light from the lens. This 5.0 x 7.0" lens shade attaches to a lens or lens hood using the included touch-tab strap, and can be bent into whatever shape you need to prevent lens flare--the shade keeps the shape you bend it into. It will also block rain from your lens (the lens shade is made from waterproof ballistic nylon with double-stitch sewing and finished edges). The Flex Lens Shade weighs just 1.2 oz (34 g) and lies flat for easy storage and transport.
